Untangling Rosalind Franklin’s Role in DNA Discovery, 70 Years On
On April 25, 1953, James Watson and Francis Crick revealed a landmark paper in Nature, proposing the double helix because the lengthy elusive construction of DNA, a discovery {that a} decade later earned the lads the Nobel Prize in Physiology or Drugs.
Within the remaining paragraph of the paper, they acknowledged that that they had been “stimulated by a information of the overall nature of the unpublished experimental outcomes and concepts” of two scientists at King’s School London, Maurice Wilkins and Rosalind Franklin.
Within the 70 years since, a much less flattering story has emerged, thanks largely to Dr. Watson’s personal best-selling ebook, “The Double Helix.” Within the ebook, he not solely wrote disparagingly of Dr. Franklin, whom he referred to as Rosy, but in addition mentioned that he and Dr. Crick had used her knowledge with out her information.
“Rosy, after all, didn’t instantly give us her knowledge,” Dr. Watson wrote. “For that matter, nobody at King’s realized they have been in our fingers.”
This account turned a parable of poor scientific habits, resulting in a backlash in opposition to Dr. Watson and Dr. Crick and turning Dr. Franklin right into a feminist icon. It additionally set off a long-running debate amongst historians: Exactly what position did Dr. Franklin play within the discovery of the double helix, and to what extent was she wronged?
In a brand new opinion essay, revealed in Nature on Tuesday, two students argue that what transpired “was much less malicious than is broadly assumed.” The students, Matthew Cobb, a zoologist and historian on the College of Manchester who’s writing a biography of Dr. Crick, and Nathaniel Consolation, a historian of drugs at Johns Hopkins College who’s writing a biography of Dr. Watson, draw upon two beforehand missed paperwork in Dr. Franklin’s archive.
These paperwork, they are saying, recommend that Dr. Franklin knew that Dr. Watson and Dr. Crick had entry to her knowledge and that she and Dr. Wilkins collaborated with them. “We needs to be pondering of Rosalind Franklin, not because the sufferer of DNA, however as an equal contributor and collaborator to the construction,” Dr. Consolation mentioned.
Different specialists mentioned that the brand new paperwork have been attention-grabbing however didn’t seriously change the narrative; it has lengthy been clear that Dr. Franklin performed a key position within the discovery. “What this does is add a bit new proof to a path, which leads on to Franklin’s being a significant participant,” mentioned David Oshinsky, a historian of drugs at New York College.
And no matter what Dr. Franklin knew about who had entry to her knowledge, the brand new paperwork don’t change the truth that she didn’t obtain ample recognition for her work, some historians mentioned.
“What’s unequal and has all the time been unequal and continues to be unequal about Rosalind Franklin is the credit score that she didn’t get within the aftermath of the invention,” mentioned Dr. Jacalyn Duffin, a hematologist and historian of drugs at Queen’s College, in Canada.
Seeing double
Within the early Nineteen Fifties, Dr. Watson and Dr. Crick have been working collectively on the College of Cambridge, in Britain, making an attempt to piece collectively the construction of DNA, largely by constructing fashions of the molecule.
At close by Kings School London, Dr. Franklin and Dr. Wilkins have been making an attempt to resolve the identical puzzle experimentally, utilizing X-rays to create photographs of DNA. (That they had a famously fractious relationship, and largely labored individually.)
In “The Double Helix,” Dr. Watson advised that his breakthrough got here after Dr. Wilkins confirmed him considered one of Dr. Franklin’s photographs, generally known as {Photograph} 51. “The moment I noticed the image my mouth fell open and my pulse started to race,” Dr. Watson wrote.
That ebook was revealed in 1968, a decade after Dr. Franklin died of ovarian most cancers at age 37, and it turned the prevailing narrative of the invention. However the true story was extra advanced.
In December 1952, Dr. Crick’s supervisor, the molecular biologist Max Perutz, acquired a report on Dr. Franklin’s unpublished outcomes throughout an official go to to King’s School. Dr. Perutz later gave this report back to Dr. Crick and Dr. Watson.
This knowledge proved extra helpful to the pair than {Photograph} 51, mentioned Dr. Cobb and Dr. Consolation, who discovered a letter that suggests Dr. Franklin knew her outcomes had made their technique to Cambridge.
Within the letter, which was written in January 1953, Pauline Cowan, a scientist at King’s School, invited Dr. Crick to an upcoming discuss by Dr. Franklin and her scholar. However, Dr. Cowan wrote, Dr. Franklin and her scholar mentioned that Dr. Perutz “already is aware of extra about it than they’re more likely to get throughout so it’s possible you’ll not assume it worthwhile coming.”
That letter “strongly suggests” that Dr. Franklin knew the Cambridge researchers had entry to her knowledge and that she “doesn’t appear to have minded,” Dr. Cobb mentioned.
Dr. Cobb and Dr. Consolation additionally discovered a draft of a never-published Time journal article in regards to the discovery of the double helix. The draft characterised the analysis not as a race however because the product of two groups that have been working in parallel and sometimes conferring with one another.
“It portrays the work on the double helix, the fixing of the double helix, because the work of 4 equal contributors,” Dr. Consolation mentioned.
A query of credit score
Elspeth Garman, a molecular biophysicist on the College of Oxford, mentioned that she agreed with Dr. Consolation and Dr. Cobb’s conclusion, saying, “They received proper that she was a full participant.”
However Dr. Perutz’s sharing of Dr. Franklin’s unpublished knowledge is “barely iffy,” she mentioned. (In 1969, Dr. Perutz wrote that the report was not confidential however that he ought to have requested for permission to share it “as a matter of courtesy.”)
Nonetheless, different scientists and historians mentioned they have been puzzled by the arguments made within the Nature essay. Helen Berman, a structural biologist at Rutgers College, referred to as them “form of unusual.” Of Dr. Franklin, she mentioned, “If she was an equal member, then I don’t know that she was handled very nicely.”
Dr. Franklin and Dr. Wilkins every revealed their very own leads to the identical challenge of Nature that included Dr. Watson and Dr. Crick’s report, as a part of a bundle of papers. However Dr. Berman questioned why the scientists didn’t collaborate on a single paper with shared authorship. And a number of other students mentioned that they thought the brand new essay minimized the wrongdoing by the Cambridge workforce.
Dr. Consolation mentioned that he and Dr. Cobb weren’t “making an attempt to exonerate” Dr. Watson and Dr. Crick, whom he mentioned have been “gradual to completely acknowledge” Dr. Franklin’s contribution. Dr. Cobb mentioned that the Cambridge scientists ought to have informed Dr. Franklin that they have been utilizing her knowledge. “They have been ungallant,” he mentioned. “They weren’t as open as they need to have been.” However, he added, it wasn’t “theft.”
There is no such thing as a proof that Dr. Franklin felt aggrieved by what occurred, historians mentioned, and she or he turned pleasant with the Cambridge duo within the remaining years of her transient life. “So far as I can inform, there was no dangerous feeling,” Dr. Oshinksy mentioned.
Which may have modified had Dr. Franklin lived lengthy sufficient to learn “The Double Helix,” a number of students famous. “‘The Double Helix’ is simply appalling,” Dr. Garman mentioned. “It offers a really, very slanted view, and doesn’t give her the credit score for the bits that they even used from her.”
Dr. Franklin’s early demise additionally meant she missed out on the Nobel Prize, however the Nobel Meeting may have discovered different methods to acknowledge her contribution, mentioned Nils Hansson, a historian of drugs at Heinrich Heine College Düsseldorf, in Germany. Neither Dr. Watson nor Dr. Crick talked about her after they accepted their awards, Dr. Hansson famous, though Dr. Wilkins, who additionally acquired the prize, did.
“She really did get a uncooked deal,” mentioned Dr. Howard Markel, a doctor and historian of drugs on the College of Michigan and the creator of “The Secret of Life,” a ebook in regards to the discovery of the double helix. “Everybody likes to obtain correct credit score for his or her work. Everybody ought to care sufficient about their colleagues to make sure the method of truthful play.”

Kennedy’s Plan for the Drug Crisis: A Network of ‘Healing Farms’
Though Mr. Kennedy’s embrace of recovery farms may be novel, the concept stretches back almost a century. In 1935, the government opened the United States Narcotic Farm in Lexington, Ky., to research and treat addiction. Over the years, residents included Chet Baker and William S. Burroughs (who portrayed the institution in his novel, “Junkie: Confessions of an Unredeemed Drug Addict”). The program had high relapse rates and was tainted by drug experiments on human subjects. By 1975, as local treatment centers began to proliferate around the country, the program closed.
In America, therapeutic communities for addiction treatment became popular in the 1960s and ’70s. Some, like Synanon, became notorious for cultlike, abusive environments. There are now perhaps 3,000 worldwide, researchers estimate, including one that Mr. Kennedy has also praised — San Patrignano, an Italian program whose centerpiece is a highly regarded bakery, staffed by residents.
“If we do go down the road of large government-funded therapeutic communities, I’d want to see some oversight to ensure they live up to modern standards,” said Dr. Sabet, who is now president of the Foundation for Drug Policy Solutions. “We should get rid of the false dichotomy, too, between these approaches and medications, since we know they can work together for some people.”
Should Mr. Kennedy be confirmed, his authority to establish healing farms would be uncertain. Building federal treatment farms in “depressed rural areas,” as he said in his documentary, presumably on public land, would hit political and legal roadblocks. Fully legalizing and taxing cannabis to pay for the farms would require congressional action.
In the concluding moments of the documentary, Mr. Kennedy invoked Carl Jung, the Swiss psychiatrist whose views on spirituality influenced Alcoholics Anonymous. Dr. Jung, he said, felt that “people who believed in God got better faster and that their recovery was more durable and enduring than people who didn’t.”

Children exposed to higher fluoride levels found to have lower IQs, study reveals
The debate about the benefits and risks of fluoride is ongoing, as RFK Jr. — incoming President Trump’s pick for HHS secretary — pushes to remove it from the U.S. water supply.
“Fluoride is an industrial waste associated with arthritis, bone fractures, bone cancer, IQ loss, neurodevelopmental disorders and thyroid disease,” RFK wrote in a post on X in November.
A new study published in JAMA Pediatrics on Jan. 6 found another correlation between fluoride exposure and children’s IQs.
RFK JR. CALLS FOR REMOVAL OF FLUORIDE FROM DRINKING WATER, SPARKING DEBATE
Study co-author Kyla Taylor, PhD, who is based in North Carolina, noted that fluoridated water has been used “for decades” to reduce dental cavities and improve oral health.
“However, there is concern that pregnant women and children are getting fluoride from many sources, including drinking water, water-added foods and beverages, teas, toothpaste, floss and mouthwash, and that their total fluoride exposure is too high and may affect fetal, infant and child neurodevelopment,” she told Fox News Digital.
The new research, led by scientists at the National Institute of Environmental Health Sciences (NIEHS), analyzed 74 epidemiological studies on children’s IQ and fluoride exposure.
FEDERAL JUDGE ORDERS EPA FURTHER REGULATE FLUORIDE IN DRINKING WATER DUE TO CONCERNS OVER LOWERED IQ IN KIDS
The studies measured fluoride in drinking water and urine across 10 countries, including Canada, China, Denmark, India, Iran, Mexico, Pakistan, New Zealand, Spain and Taiwan. (None were conducted in the U.S.)
The meta-analysis found a “statistically significant association” between higher fluoride exposure and lower children’s IQ scores, according to Taylor.
“[It showed] that the more fluoride a child is exposed to, the more likely that child’s IQ will be lower than if they were not exposed,” she said.
These results were consistent with six previous meta-analyses, all of which reported the same “statistically significant inverse associations” between fluoride exposure and children’s IQs, Taylor emphasized.
The research found that for every 1mg/L increase in urinary fluoride, there was a 1.63-point decrease in IQ.
‘Safe’ exposure levels
The World Health Organization (WHO) has established 1.5mg/L as the “upper safe limit” of fluoride in drinking water.
“There is concern that pregnant women and children are getting fluoride from many sources.”
Meanwhile, the U.S. Public Health Service recommends a fluoride concentration of 0.7 mg/L in drinking water.
“There was not enough data to determine if 0.7 mg/L of fluoride exposure in drinking water affected children’s IQs,” Taylor noted.
FDA BANS RED FOOD DYE DUE TO POTENTIAL CANCER RISK
Higher levels of the chemical can be found in wells and community water serving nearly three million people in the U.S., the researcher noted.
She encouraged pregnant women and parents of small children to be mindful of their total fluoride intake.
“If their water is fluoridated, they may wish to replace tap water with low-fluoride bottled water, like purified water, and limit exposure from other sources, such as dental products or black tea,” she said.
“Parents can use low-fluoride bottled water to mix with powdered infant formula and limit use of fluoridated toothpaste by young children.”

While the research did not intend to address broader public health implications of water fluoridation in the U.S., Taylor suggested that the findings could help inform future research into the impact of fluoride on children’s health.
Dental health expert shares cautions
In response to this study and other previous research, Dr. Ellie Phillips, DDS, an oral health educator based in Austin, Texas, told Fox News Digital that she does not support water fluoridation.
“I join those who vehemently oppose public water fluoridation, and I question why our water supplies are still fluoridated in the 21st century,” she wrote in an email.
“There are non-fluoridated cities and countries where the public enjoy high levels of oral health, which in some cases appear better than those that are fluoridated.”

Phillips called the fluoride debate “confusing” even among dentists, as the American Dental Association (ADA) advocates for fluoride use for cavity prevention through water fluoridation, toothpaste and mouthwash — “sometimes in high concentrations.”
“[But] biologic (holistic) dentists generally encourage their patients to fear fluoride and avoid its use entirely, even if their teeth are ravaged by tooth decay,” she said.
“Topical fluoride is beneficial, while systemic consumption poses risks.”
Phillips encouraged the public to consider varying fluoride compounds, the effect of different concentrations and the “extreme difference” between applying fluoride topically and ingesting it.
“Topical fluoride is beneficial, while systemic consumption poses risks,” she cautioned.
“Individuals must take charge of their own oral health using natural and informed strategies.”
The study received funding from the National Institute of Environmental Health Sciences (NIEHS), the National Institutes of Health (NIH) and the Intramural Research Program.
